Strabismus

This trial tests a computer-based training method designed to improve stereo vision, or depth perception, in adults with conditions like amblyopia (lazy eye) or strabismus (misaligned eyes). Participants aged 18 to 39 with impaired depth perception will be randomly assigned to ei…

This study tests whether injecting Botox into the eye muscles can correct strabismus (misaligned eyes) without surgery. 127 children and adults with small-to-moderate eye turns will receive Botox injections, and their eye alignment will be tracked for a year. The goal is to see i…

This study will check if an AI system can accurately measure eye movements from smartphone videos. About 1,000 adults with suspected eye movement issues will record a short video while following a moving target. The AI's measurements will be compared to expert ratings to see if i…

This study compares two anesthesia methods for strabismus (eye muscle) surgery in adults: general anesthesia (being fully asleep) versus a combination of sedation with a local numbing injection around the eye. Researchers will measure patient and surgeon satisfaction with each ap…

This study tests whether watching 3D movies can improve depth perception and vision in children aged 4 to 12 who still have some vision loss from lazy eye (amblyopia) despite prior treatment. Forty children will be randomly assigned to watch three movies in either 3D or 2D, then …

This study builds a large registry of strabismus patients in Japan to evaluate how well different treatments—from surgery to simple observation—work in everyday practice. By analyzing outcomes for common, rare, and complex cases, researchers hope to identify which approaches succ…

This study follows 62 people who need a second surgery for crossed or wandering eyes (strabismus). Researchers want to find out what factors increase the risk of needing repeat surgery and how successful the second operation is. Participants get a personalized surgical plan and a…

This study will measure the width of the medial rectus tendon in 28 people having surgery for crossed eyes (esotropia). The goal is to see if tendon width is linked to how much the eye position changes after surgery. If a link is found, it could help surgeons plan more precise op…
